Filter by:One of the criteria used for long-term implant success is the evaluation of radiographic bone loss. It is known that the keratinized mucosa over the alveolar crest forms a protective barrier against inflammatory infiltration. In addition, it has been reported that the vertical mucosal thickness on the crest is important in the formation of the biological width around the implant. The aim of this study was to evaluate the effect of vertical mucosal thickness on the alveolar crest on peri-implant marginal bone loss around crestal and subcrestal placed platform-switching implants. In this study, patients will be divided into 2 main groups with vertical mucosal thickness of 2 mm and less and more than 2 mm, and both groups will consist of 2 subgroups as crestally and subcrestally according to the implant level placed. A total of 80 implants will be included, 20 implants in each group. Before starting the surgery, after anesthesia is given, the width of the patient's peri-implant keratinized mucosa and the vertical mucosal thickness over the alveolar crest will be measured. Clinical and radiological measurements will be made in all patients during the prosthetic loading session (T0), at 3rd month (T1), 6th month (T2) and 1 year after loading (T3). With standardized control periapical radiographs to be taken as a result of one-year follow-up, the marginal bone loss amount in the implants will be evaluated using soft-ware.
Dental implants have become one of the most common treatments used for the rehabilitation of lost teeth. The success rate of dental implant treatment is quite high. One of the criteria used for long-term implant success is the evaluation of radiographic marginal bone loss. Implants are used at the bone and tissue level in implant treatment. In this study, it was planned to use 20 implants of the same brand, with a single implant in the bilateral posterior regions in 10 patients.The study will be designed as split-mouth. The implant will be placed at the bone level with the same protocol in the two edentulous areas and the flap will be closed primarily. After 3 months, the substructure of the two-piece abutment concept system will be placed in a region during the healing head placement stage, and the bone level implant will be converted to the tissue level. A conventional healing cap will be placed in the other area. Periapical radiographs will be taken from the patients who participated in our study, as in all implant patients, during the pre-surgical planning phase and after implant placement. With the control periapical radiographs to be taken as a result of one-year follow-up, the marginal bone loss amount in the implants will be evaluated using soft-ware. Clinical measurements will be taken in all patients at the prosthetic loading session and 1 year after loading.
Tooth extraction triggers a cascade of biological events mediated by both the local inflammatory response that follows the surgical intervention and the deprivation of masticatory stimulation of the periodontium, which elicit an alteration of the homoeostasis and structural integrity of the periodontal tissues. Bone remodeling kicks off after tooth loss and continues for several months with most changes taking place in the first three months. Interestingly, Schmidt-Schultz and Schultz, found that intact growth factors are conserved even in the collagenous extracellular matrix of ancient human bone and teeth. Thus, the application of stored dentin may have similar benefits as fresh dentin, preserving intact growth factors for a prolonged period avoiding the need to perform multiple surgical interventions simultaneously. The volume of the particulate dentin is more than twice of the original root volume. Thus, the idea of using autogenous stored mineralized dentin grafts (ASMDG) in ARP evolved.
The objective of this study will be to evaluate a new protocol for the surgical treatment of periodontal disease with two novelties: to make a single incision in the midline of the interproximal area to respect the vascular supply and preserve the granulation tissue with regenerative potential. The investigators will carry out a controlled and randomized clinical trial with a control group (n=25; modified Kirkland flap) and a test group (n=25; experimental surgical protocol: incision in the mid-interproximal area of the papilla and preservation of the granulation tissue). Clinical parameters will be taken at the time of surgery and 12 months follow-up: bleeding on probing (BoP), clinical attachment level (CAL), residual probing depth (rPD),Probing pocket depth reduction (PPDr), recession (REC), interproximal gingival recession (iGR), width of keratinized gingiva (KT), gain of supra-alveolar clinical attachment (SUPRA-AG), early wound healing index (EHI).
For patients having periodontal intrabony lesions, three treatment modalities were executed to evaluate the effect of protecting Leukocyte rich -Platelet Rich Fibrin harvests (applied in the bony defects) with resorbable collagen membranes. Clinical Outcomes recorded were the Plaque index (PI), Gingival index (GI), probing depth reduction (PD), Clinical attachment level (CAL), and radiographic defect depth changes. For the biochemical evaluation: levels of PDGF-BB and VEGF obtained from crevicular fluid by Perio-Paper strips were assessed using ELIZA.
The extent of marginal bone remodeling around the neck of dental implants has been used for many years as a criterion for defining their long-term success. Apico-coronal position represents a crucial factor in this field. This study aims to establish the optimal insertion depth of a subcrestal implant, with the aim of minimizing the bone resorption.
The aim of this trial is to compare the effect of autogenous demineralized dentin graft combined with injectable PRF loaded with metronidazole (sticky demineralized tooth releasing metronidazole) versus autogenous demineralized dentin graft (ADDG) alone on alveolar ridge preservation after extraction of non restorable, infected single-rooted teeth
Ridge preservation should be considered whenever possible after tooth extraction. Whether implant placement would be performed or for aesthetic consideration at pontic sites when conventional bridge is planned. Ridge preservation aims to maximize the bone formation accompanied with good soft tissue architecture to facilitate implant and prosthetic replacement restoring function, phonetics and aesthetics. the Aim of the study is To evaluate the bucco-lingual ridge width clinically and radiographically, height of buccal and lingual ridges of the socket after application of injectable platelet rich fibrin and autogenous dentin graft.
Immediate implant placement has proven to be a successful treatment procedure that is preferred by patients because of being less traumatic, more time-efficient. Nowadays, the main goal of a successful immediate implant treatment has ceased to be gaining stability and osseointegration, but achieving long-term dimensional stability has become the optimal challenge. Various soft tissue and hard tissue augmentation techniques have been investigated in order to maintain the ridge dimensions following extraction and immediate implant placement.
The aim of this trial is to compare the effect of autogenous demineralized dentin block graft (ADDBG) versus particulate deproteinized bovine bone graft (PDBBG) on alveolar ridge preservation after extraction of non-restorable single rooted teeth
